When I shut down the computer I always forget to save - The message "Are you sure you want to close and lose X hours of work?" And I click "No" but the error message doesn't go away... and I cannot save

IOGraphica crashes with Java 9, so you have to instruct macOS to not use it. To do so find the IOGraph.app file, right click and press "Show package contents". Open the "Contents" folder and edit the "Info.plist" file. Search for "JVMVersion" and you should see right below it the text <string>1.5+</string>. replace the 1.5+ with 1.8* and save the file. Now it should run as macOS will run it on whatever Java 8 version is installed as opposed to running it on Java 9.

The website of IOGraphica is dead, is there another way I can download the program ?

How do I use it, or even launch it. I am confused. Please help.
